A fault in Telecom's XT mobile network cutting services to thousands of customers continued tonight.
Telecom said at 10pm that a number of cell sites in areas in the lower South Island, including Dunedin, Invercargill, Timaru and Queenstown, were still affected, resulting in a loss of XT service those areas.
XT users in other areas were still experiencing intermittent service issues.
Chief executive Paul Reynolds the company would look closely at compensation claims once the problem was fixed.
"I apologise to our customers who have been inconvenienced, but also recognise that words are not enough. That's why we are taking rapid action."
Mr Reynolds had commissioned an urgent independent review to ensure Telecom was taking all reasonable steps for its customers.
XT users should call emergency services from a landline and could also check their voicemail that way
